谷子 MYB 转录因子家族与抗旱关系的研究
MYB transcription factors and their relationship with drought tolerance in foxtail millet
摘要
Abstract
Objective]MYB transcription factors are a class of protein with conserved MYB domain.They are involved in the regulation of plant growth,stress resistance and other physiological responses.Foxtail millet is an important drought-tolerance crop in northern China.It is important to explore the unique genetic resources and the molecular mechanism of drought-tolerance in foxtail millet to understand the relationship between drought resistance and MYB transcription factor family genes.[Methods]In this study,the drought-tolerant variety Go Go Mu Ji Ju (GG)and the drought sensitive variety Jin Fen 1 6 (JF)were used as experimental materials,they were treated by PEG6000 in seed-ling stage,and transcriptome sequencing was conducted with mRNA from GG and JF leaves,bioinformatics analysis were used to analyze the differentially expressed MYB transcription factors.[Results]The results showed that:there were 26 MYB transcription factor genes that showed apparent differential expression in GG and JF,in addition,the drought-tolerant regulatory elements in promoters of the corresponding genes showed different composition and distri-bution.Si034363m ,Si003539m and Si03071 1m ,which were up-regulated upon drought stress in GG,showed close homology with some MYB transcription factors that mainly involved in drought tolerance in Arabidopsis .[Conclusion] Based on the research of MYB transcription factors in foxtail millet,we speculated that 26 differentially expressed MYB transcription factor genes could be used as important drought tolerant candidate genes in foxtail millet.This study could provide a theoretical basis for the study of the molecular mechanism of drought tolerance in foxtail millet.关键词
